Abstract

The invention relates to a Pb-free deforming/partially fragmenting projectile with a projectile body. In order to improve the killing effect of the projectile, the projectile has a fragmenting core according to the invention. The projectile body is equipped with a bore which is arranged on the longitudinal axis, extends from the tip of the projectile body, and extends into the interior, and the projectile body tip, which faces away from the projectile base has a bevel which extends from the outer circumference of the projectile body to the bore and runs at an acute angle to the longitudinal axis. The fragmenting core has a cylindrical part and a head part. The cylindrical part is arranged in the bore, and the head part protrudes out of the bore and has a support surface which is adapted to the bevel in the projectile body and together with the support surface rests on the bevel of the projectile body. The head part has a rounded tip which forms the tip of the projectile.

Claims

exact text as granted — not AI-modified
The invention claimed is: 
     
       1. A lead-free partially deforming and partially fragmenting projectile comprising:
 a projectile body configured for mounting in a cartridge including a fragmentable core, a base, a bore disposed on a longitudinal axis of the body and which extends from a tip of the projectile body into an interior of the projectile body, the tip facing away from the base and including a beveled surface which forms an acute angle with the longitudinal axis and which extends from an outer circumference of the projectile body to the bore, the fragmentable core having a cylindrical part and a head part which protrudes out of the bore and has a support surface conforming to the beveled surface and rests on the support surface and the head part has a rounded tip which is the tip of the projectile; and wherein 
 the fragmentable core is deformable and is configured to start mushrooming of the projectile body upon impact with a game animal body after being fired from the cartridge, weighs between 3% and 30% of a weight of the projectile body, consists of tin or pressed tin granules and has predetermined breaking points formed into the core prior to mounting of the projectile body in the cartridge, the breaking points of the core are configured to break upon the impact with the game animal body into fragments which separate from the projectile body into the game animal body while the projectile body passes completely through the game animal body. 
 
     
     
       2. A projectile in accordance with  claim 1 , wherein the body consists of deformable lead-free material or alloys thereof. 
     
     
       3. A projectile in accordance with  claim 2 , wherein the body consists of Cu or CuZn. 
     
     
       4. A projectile in accordance with  claim 3 , wherein the bore has only a cylindrical surface. 
     
     
       5. The projectile in accordance with  claim 3 , wherein the bore is entirely filled with the core. 
     
     
       6. A projectile in accordance with  claim 2 , wherein the bore has only a cylindrical surface. 
     
     
       7. The projectile in accordance with  claim 2 , wherein the bore is entirely filled with the core. 
     
     
       8. A projectile in accordance with  claim 1 , wherein the bore has only a cylindrical surface. 
     
     
       9. The projectile in accordance with  claim 8 , wherein the bore is entirely filled with the core. 
     
     
       10. The projectile in accordance with  claim 1 , wherein the bore is entirely filled with the core.
